I know I have multiple copies already but they make such great donor carts for other games. Let me see if I can find my spreadsheet of what I have already.
Then I might make you an offer for
Double Dribble
Fester's Quest
Rush'n Attack
Tecmo Bowl
Trojan
Who or how did you do the ROM swaps? Wanted to try tinkering with this myself to see what I could get to run.
If you were closer I would try to make a deal.
If you have not tried troubleshooting already.
That black dongle with hdmi cable plugs into that open vga port on the jamma adapter for video and you need a male to male audio cable connecting that audio jack on same black dongle to the audio jack on the jamma adapter board for sound.
Is this just the player control panel side of the wiring harness or the whole harness including the Jamma connector on the other end? Did not see it in the pictures.
I am looking for a complete wiring harness for a Gauntlet Legends rebuild.
